GEORGE WILLIAMS, OF S'] RLING, COLORADO TERRITORY.

IMPROVED ORE AND TIMBER CAR FOR MINES.

Specification forming part of Lett rs Patent No. 56,480, dated July 17,1866.

To all whom 'it may cmcrn:

Be it known that I, GEORGE WILLTAMs, of Sterling, in the county of Parkand Territory of Colorado, have made a new and useful Improvement inCombined Ore and Timber Car for Mines; and I do hereby declare thefollowing to be a full, clear, and exact description of the nature,Construction, and operation of the same, sufficient to enable oneskilled in the art to which it appertains to construct and use the same,reference being had to the acconpanying drawings, which are made part ofthis specifica-tion, and in which- Figure l is a vertical longitudinalsection, showing the ends of the car down in order to travel as auorecar. Fig. 2 is a vertical lon gitudinal section of car arranged forcarrying timber. Fig. 3 is a vertical longitudinal section, showing thecar in the act of dumping. Fig. 4 is an end elevation, showing the carin the crevice. the detachable handle by which the hand-car is moved.

The improvement in the Construction of the car, which is to be drawn ordriven by manual power in the crevice of the mine, consists in soconstructing the ends that they shall be self-supporting, either againstthe ends or upper edges of the sides of the car; in the arrangementwhereby the car is adapted for containing ore or long timbers in thearraugement for tripping the door-fastenng, and n the detachable handlefor manipulating the car.

In the drawings, A A are the sides of the car, which are notched at a,so that the door B may shut partially against and partially within thesides, as shown in Figs. 1 and 5, the under portion, b, of the doorshutting against the end in the notch a. This arrangement secures thedoor from displacenent in any direction save the one in which it issecured by the latch C, which is pivoted underneath the car in such amanner as to be actuated by the post D, which is placed in the track soas to trip the trigger at the desired point.

A blow or pressure against the forward end or beneath the outer end ofthe trigger will not open it, but it requires the contact of the post Dwith the inner end, which is attained when the car arrives at thedischarging-point. (See Fig. 3.)

Fig. 5 is a perspective view of In the condition shown in Fig. 1 the caris prepared to carry ore, rock, or the detritus of the mine to the pointof discharge, and in the condition shown in Fig. 2 it is prepared forcarrying timbers into the mine for the support of the root' and sides,for laying track, or other uses familiar to mining experts.

The conversion from the condition Fig. 1 to that shown in Fig. 2 is nadeby raising the doors and folding them over, so as to form a temporaryroot', the wide portions b b resting upon the upper edge of the sides asthey before rested against the ends. I

The swinging handle, Fig. 5, is provided as a matter ot' convenience andsecurity to the hands, which are thereby less exposed than when graspingthe exposed upper edge of the door.

The car is designed to be used in crevices which have been opened by theremoval of pay-rock, and the arrangement of duplicate doors permits theuse of it without turning from either direction toward a common downcastshaft when used by two sets of miners whose tracks approach a commonpoint of discharge from two .lifferent directions, and who use the caralternately.

The arrangement for change in the condition oi' the car permits it tocarry loads each way with but little trouble in conversion,instead ofcompelling one car to be removed before the other can be put inposition.

The form of the doors enables them to be supported by the sides withoutbraces, cleats, or bars, and gives no occasion for the accumulation oftrash therein or difficulty of dis charge theret'rom.

What I claim as new is l. The construction ot" the doors with a widerportion, b, to adapt them to be supported by the sides of the car,substantially as described.

2. A car constructed with end doors adapted to be folded over the top,for the purpose of converting it into a timber-car.

3. In combination with the above, a trigger, 0, provided with an inwardprojection adapted to be tripped by the post D.
